Port apparatus and sheath device for electrocautery and related methods thereof

Abstract

A method and apparatus for performing electrocautery on a site of a subject that includes inserting a trocar device into the location of the site of the subject and electro-cauterizing the site of the subject using a diode included with the trocar device. A method and apparatus for performing electrocautery on a site of a subject that includes inserting one or more medical tubes or medical instruments or devices that extends through an expandable sheath; and electro-cauterizing the site of the subject using a diode included with the expandable sheath device.

We claim: 
     
       1. A port apparatus for use for providing electrocautery for surgery on a site of a subject, said device comprising:
 an expandable sheath device, wherein said expandable sheath device having a distal portion and a proximal portion separated longitudinally from one another, wherein said expandable sheath has a tip at said distal portion; 
 a diode disposed on said distal portion of said expandable sheath device, wherein position of said diode is longitudinally spaced from said tip of said expandable sheath toward said proximal portion of said expandable sheath; 
 an electro-surgical terminal disposed on said proximal portion of said expandable sheath device; 
 a wire disposed longitudinally on said expandable sheath device, wherein said wire is in communication with said diode and said electro-surgical terminal; 
 a trocar device, wherein said expandable sheath device is configured to receive said trocar device that extends longitudinally through said expandable sheath; 
 a dilator, wherein said trocar device is configured to receive said dilator that extends longitudinally through said trocar device; and 
 said expandable sheath is configured to expand radially outward into an expanded state upon receiving said trocar device that has a radius larger than the radius of said expandable sheath in an unexpanded state. 
 
     
     
       2. The port apparatus of  claim 1 , wherein said apparatus is configured for use as a laparoscopic or thoracoscopic port for laparoscopic or thoracoscopic surgery, respectively. 
     
     
       3. The port apparatus of  claim 1 , wherein:
 said trocar device is configured to receive a needle that extends longitudinally through said trocar device.
